WILLIAM THOMAS WATSON, '0F VANCOUVER, BRITISH COLUMBIA, CANADA.

WHEEL FOR TOYS.

Application filed November 19, 1917.

To all 'whom t may concern.'

Be it known that I, VILLIAM THOMAS lVArsoN, a subject of the King ofGreat Britain, and a resident of the city of Vancouver, in the Provinceof British Columbia, Canada, have invented certain new and usefulImprovements in Vheels for Toys, of whiclithe following is a.specification.

My invention relates to improvements in wheels for toys, and the objectof my` invention is to devise a wood wheel provided with a metallic rimadapted to be secured to y the periphery of the wheel without the use ofnails, glue or any other. like means of fastening so as to form, whensecured in place, a permanent part of the wheel itself, the use of whichrim makes it possible to use, with highly efiicient results, practicallyany kind of cheap wood in the construction of the wheels, thereby doingaway with the necessity of using kexpensive hardwood, as is a commonpractice at the present time. A further object is to provide a wheel ofthis character which is capable of beingmanufactured in a simple,inexpensive, and eX- peditious manner, and the running of which when inuse is rendered practically noiseless on account of the peculiarconstruction of the metallic rim.

I attain these objects'by the construction illustrated in theaccompanying drawings in which Figure l is a side elevation of thewheel.

Fig. 2 is a front View7 looking on the rim.

Fig. 3 is a fragmentary sectional View, taken through the groove of therim.

Fig. e is a fragmentary sectional view, taken through the rim.

Fig.A 5 is a cross section of the wheel, taken through the line am?) inFig. l.

Fig. 6 is an enlarged fragmentary view, in cross section, of the rim.

Fig. 7 is a view showing the metal strip before attachment to the wheel.

Similar figures of reference indicate similar parts throughout theseveral views.

1 indicates the wood wheel, provided with the usual axle opening 2 andwhich wheel may be lightened if desired by cutting out of it openingssuch as indicated at 3 in Fig. l, or it may be made as a spoked wheel. Aindicates the metallic rim secured to the periphery of the wheel l andwhich rim, prior to its attachment to the wheel, consists of a fiatstrip of metal, shown in Fig. 7, of suitable thickness and of sufcientlength Specification of Letters Patent.

to encircle thewheel so that one end overlaps the other.,

In construction, a cut is made in the periphery of the wheel, .which isthen placed in a suitable machine capable of rotating it at a desiredspeed. rim 4 being reduced in width, as shown at 9 in Fig. 7, andinserted in the cut 5, the machine is set in motion, rotating the wheelin a direction to draw the strip 4l on to its periphery, when suitableappliances with which the machine is provided press the stripdownwardlyalong its peripheral center line so that a groove 6 is formed, at thesame time turning the edges of the strip inwardly and sinking them intothe sides of the wheel,.as indicated at 7 and 8 in Figs. :2, 5, and 6,the wheel being rotated untiLthe strip encircles it so that the otherend overlaps the end which was fixed in the cut 5.

The rim thus formed then appears as shown in Figs. 2, 5, and 6, and itwill be seen that it is immovably iiXed to the wheel, as the grooving ofthe strip sinks the metal into the wood along the peripheral center lineof the wheel so that the woodis thereby spready and crowded, as it were,into the turned over edges of the strip, and the en tire operationbeingeffected under pressure, the finished rim. is rigidly and securelyfastened to the periphery of the wheel and this without the aid ofnails,.glue, or any other like means of fastening.

Instead of employing the method of attachment described in the foregoingI may prefer to first of all form the rim on a forming wheel on whichthe rim is formed circular and the edges turned straight inward,thereafter applying the rim so formed to the wheel and then completingthe operation by grooving the rim as already described and clenching theedges into the sides of the wheel.

The axle opening 2, while it may be simply a hole formed in the body ofthe wheel, is preferably litted with a metallic liner, which consists ofthimbles l0 and l1, each of which is flanged at one end, inserted fromopposite sides of the opening one within the other and swaged over oneach unfianged end so that the unflanged end of thimble l0 is clenchedinto the body of the wheel and the unflanged end of thimble 11 is turnedover on t0 the flange of thimble l0, from which it will be seen that adouble hub sleeve is formed secured to the wheel body One end of thestrip or Without the aid et any separate means of fastening.

llhat l claim as iny invention is l. ln a Wheel of the characterdescribed, a riin having a groove extending circumferentiallytherearound and sunlr into the periphery of the Wheel.

2. ln a Wheel of the character described, a rim having its oppositeedges secured to the sides of the Wheel and having a groove sunk intothe periphery of the Wheel.

3. ln a Wheel of the character described, a single integral metallic rimsunl into the AWheel along its peripheral center line and haring itsedges sunk into the sides of the wheel.

it. ln a Wheel ot the character described, a metallic rim haring one endiiXed into the Wheel and its other end overlapping the ixed end, saidrim having a groove formed therein along its peripheral center line andsunk into the Wheel and having its edges sunk into the opposite sides ofthe Wheel.

5. A. wheel for toys comprising a Wheel body, a metallic rim on theperiphery thereet the edges of which are turned downwardly and sunk intothe sides of the Wheel body, the said rim being grooyedcir-cumierentially and sunk into the peripheral portion of the Wheel tospread the body material on each side of the said groove and draw thesunk edges of the rim inwardly.

6. The method of making wheels for toys which consists in rst forming aWooden Wheel, fixing thereto one end of a metallic strip of greaterWidth than the Wheel thiol@ ness, rotating' the Wheel to draw the saidstrip thereonto, and then simultaneous y sinking the strip into theWheel along its penaemse ripheral center line and turning and sinking 40its edges into the opposite sides of the Wheel.

y7. The method ot making Wheels for toys which consists in Wrappingunder pressure a metal strip around the periphery of a wooden Wheellongitudinally groot/ing the strip embedding it in the periphery ot thewheel thereby forcing the peripheral portion ot the Wheel outwardly ateach side of the center and simultaneously clenching the edges of thestrip to the out-pressed sides of the Wheel.

S. ln a Wheel oi' the character described, a hub sleeve consisting oi apair of thiinbles inserted into the axle opening one within the other,said thinibles being danged at one end and swaged over on theirunfianged ends so that the untianged end of the outer thimble isclenched into the Wheel body and the unflanged end oi' the innerthii'nble is flanged over on to the flange of the outer thiinble.

9. In a Wheel of the character described, a metallic rim having one endbent over and inserted into the Wheel periphery and its other endoverlapping the inserted end, the

said rim having its edges clenched into the V sides of the Wheel.

l0. ln a Wheel of the character described, a metallic rim having one endreduced in Width and bent over and inserted into the Wheel peripheryyand its other end oyerlapping the reduced inserted end, the said rimhaving its edges clenched into the sides of the Wheel so that acontinuous clench is formed therearound.
